2 claims.

This invention relates to motors, and more particularly vibration motors. It is the purpose of the invention to provide mechanism which will be operated by vibration and which will not require any power or fuel. While I have shown my invention as applied to an advertising sign for the purposes of illustration, its use is not limited to advertising signs and it may be applied to any number of purposes.

An object of the invention is to provide a vibration motor which will be simple in construction and operation and which will contain a minimum of parts.

A further object is to provide a device of the character described, which may be cheaply made out of inexpensive materials and which will not be subject to excessive wear or breakage.

With these and other objects in mind, which will become apparent as the description proceeds, reference is had to the accompanying drawing, in which- Fig. 1 is a side elevation of an advertisement embodying my invention;

Fig. 2 is a side elevation in section showing the operation thereof, taken on the line 2-2 of Fig. 4;

Fig. 3 is a view of the disk partly shown in Fig. 1;

Fig. 4 is a plan view, partly in section, taken on the line 4 4 of Fig. 2.

Solely for the purpose of describing and illustrating my invention, I will cover one use thereof, namely, the use with an advertising sign wherein it is desired to have moving parts.

As shown in Fig. 1, the sign I presents a hand I I pouring liquid I2 from a can I3 into a glass I4 while smoke I5 is shown moving from a cigarette I6. The portions I1 and I8 are cut out in the face of the sign to present a View of a portion of the disk I9. It will be seen that as the disk I9 is rotated, the liquid shown as I2 will give the appearance of owing from the can I3 to the glass I4, while the movement in the center 20 of the disk I9 will give the effect of smoke coming from the cigarette.

To accomplish this result I provide a frame 25 having supporting members 26 and 21 through which extends an axle 2B. The disk I9 is mounted on the axle 28 and rotates therewith. Also mounted on the axle 28 between the supports 26 and 21 is a second disk 29 which, if desired, may have a serrated periphery.

Pivoted to the frame 25 at 30 is an armr 3| which has afxed to it a yoke 32. Pivotally mounted in the yoke 32 at 33 is an arm 34 having at its outer end a cog 35 andthese parts constituting a pawl. A rod 36 carrying a weight 31 is also provided to hold the cog 35 in contact with the disk 29. Pivotally mounted to the extension 4I) of the frame 25 at 4I is an additional arm 42 bearing a cog 43. The end of the arm 42 is provided with replaceable weights 44 to predetermine the tension of the cog 43 against the disk 29.

Mounted on the frame 25 at 45 is a at spring member 46 having a weighted end 41. The weight 48 is mounted in such a way that it may be replaced by a heavier or lighter weight, as its use demands. The yoke 32 has a depending portion 49 which engages the spring 46. Since the spring 46 is fastened only at 45 and is weighted at its other end, any vibration will cause the spring to move. This movement is transmitted through the yoke 32 to the arm 34 and will cause the cog 35 to rise and fall. In view of the angle of the cog 43, the disk 29 may only rotate in one direction, Consequently, the movement of the cog 35 will cause the disk to rotate, as shown in the drawing, in a counter-clockwise direction. This motion is transmitted through the axle 28 to the disk I9 to produce the desired eiect.

Quite obviously, the weight of the motor may be increased or decreased depending upon the type of work that it is to perform, and the size and thickness thereof may likewise be regulated to accommodate it to the desired use. Similarly, the materials used may vary with the circum.- stances, and numerous other modications'may be made Without departing from the spirit of my invention.

I claim:

1. A vibration motor, including a frame, al

shaft in said frame, a circular member mounted on said shaft, an arm pivoted in said frame and having a depending member, a second arm pivoted to said rst arm and having a cog engag-` ing the periphery of said circular member, means connected with the second arm for maintaining said cog in engagement with said circular member, means for limiting the rotation of said circular member to one direction, and a vibratory memberfastened at one end to said frame and weighted at the other end engaging said depending member, whereby the vibrations of said vibratory member are transmitted to said cog through the second arm to rotate said circular member.

2. In a vibration motor, a rotary circular disk, a pivotally mounted arm, a pivoted pawl on said arm contacting the disk in a manner to cause rotary lmovement of the'disk upon the pivotal movement of said arm, a weighted member connected with said pawl below the pivot thereof to keep the pawl in contact with the disk, a vibratory member, and a depending member on the free end of said arm in contact with said vibratory member, whereby the vibration of the vibratory member will cause the operation of said pawl subject to the influence of said Weighted member, to cause the rotatory movement of the disk.
